DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Some embodiments of the present invention will now be described in greater detail. Nevertheless, it should be noted that the present invention can be practiced in a wide range of other embodiments besides those explicitly described, and the scope of the present invention is expressly not limited except as specified in the accompanying claims.

Moreover, some irrelevant details are not drawn in order to make the illustrations concise and to provide a clear description for easily understanding the present invention.

Recording voice in the present invention means, in one embodiment, an electronic device records surrounding voice by its own built-in hardware and software. The electronic device records voice and saves it as an audio file by the signal process steps such as sampling, encoding, and/or compressing. The present invention does not limit to the format, sampling rate, encoding, and/or compressing ratio of the audio file. In another embodiment, the electronic device can play audio in some formats and the audio through signal process can become an audio file. For example, the electronic device could real-time download the audio information from the network server, and also could receive the audio information from the input port. However, in some embodiment, the electronic device could receive audio information from several sources not only one. In other words, the electronic device could mix several audio information to comprise a new audio file.

The touch traces in the present invention could include the panel/screen traces touched or approached by pen, and also could include the panel/screen traces touched or approached by finger(s). In some embodiments, the touch panel/screen could identify each pen in several pens. The present invention does not limit to touch technologies, whatever, such as resistive, capacitive, projective capacitive, surface acoustic wave, optical projective, and etc. The touch technologies which can generate touch traces are all applied to the present invention.

As those mentioned above, the present invention intends to solve the problem is that recording touch traces and voice at the same time to make the two media be able to relate to each other at time. In one embodiment of the present invention, it could use an integrated recording application program to run the abovementioned recording voice and recording touch traces and the time relation between two of them. In one embodiment, the voice can be recorded in a file with other data. In another embodiment, the voice and other data can be recorded in several different files having relations to each other. The files can be played individually and independently. And also, the files could be integrated to play several ones with relations to each other.

In one embodiment of the present invention, it could use a voice-recording program and a touch-trace-recording application program to record voice and other data in several different files having relations to each other. The files can be played individually and independently. And also, the files could be integrated to play several ones with relations to each other.

Referring to FIG. 1, touch traces for one preferred embodiment in accordance with the present invention are illustrated. The touch area of a touch panel 100, in FIG. 1, is divided into several regions. In the embodiment of FIG. 1, the abovementioned regions are all squares and the area of each square is the same to each other. These squares are separated to 6 lines and each line has 10 squares. In other embodiments, the regions can be other shapes, such as rectangle or hexagon, and the area of each region could be different. In one embodiment, a region touched frequently can be divided into more sub-regions, and the area of each sub-region is smaller. The present invention does not limit to the number, shape, and area of these regions.

In the embodiment of FIG. 1, it includes 4 touch traces 110-140 with time sequence to form a smile sign. When a touch point is detected, the electronic device determines whether the touch point locates in a new region. In other words, the electronic device determines whether the touch point locates in different region to the preceding touch point. For example, when the first point of touch trace 110 entering region C3 is detected, the electronic device records a timing related to region C3.

The timing could be the time in the electronic device, and also could be the time related to a timing in the audio file. For example, it could be the timing related to the beginning of audio file, and also could be a period related to the preceding recorded timing. The time resolution for each electronic device using in recording could be different, some accurate to one-hundredth of a second and some accurate to one-millionth of a second. The timing for each recording allows inaccuracy or intended adjustment to align the data structure, such as frame structure. The present invention does not limit the form and resolution to timing, all need to do is to relate touch traces to the audio file.

When the touch trace 110 leaves region C3 to enter region B3, and the first touch point of the touch trace 110 in region B3 is detected, the electronic device records a timing related to region B3 since the first touch point in region B3 is different to the preceding touch point in region C3. Similarly, When the touch trace 110 leaves region B3 to enter region B4, and the first touch point of the touch trace 110 in region B4 is detected, the electronic device records a timing related to region B4 because the first touch point in region B4 is different to the preceding touch point in region B3, and so on.

Referring to Table 1, a relation data table for one preferred embodiment of the present invention is shown. The embodiment in Table 1 does not consider touch trace(s) but the relation between touch point(s) and region(s). In the embodiment of FIG. 1, the touch area of the touch panel 100 has 60 regions, and hence the relation data table has 60 regions in maximum and the timings related to these regions. In Table 1, the regions without being touched are ignored and are not recorded for saving the memory space. Of course, if the memory space does not take into consideration, all regions can be recorded to faster the speed of recording and restoring data.

TABLE 1 region relating timing (corresponding) B3 00h:00m:01s:21 B4 00h:00m:01s:31 B5 00h:00m:01s:41 B7 00h:00m:02s:11 B8 00h:00m:02s:21 B9 00h:00m:02s:31 C3 00h:00m:01s:11 C9 00h:00m:02s:41 E5 00h:00m:03s:11 00h:00m:04s:11 E6 00h:00m:03s:21 E7 00h:00m:03s:31 00h:00m:04s:51 F5 00h:00m:04s:21 F6 00h:00m:04s:31 F7 00h:00m:04s:41

It's worth noting that the regions E5 and E7 individually relate to two timings. The first timing is recorded for touch trace 130's entering and the second timing is recorded for touch trace 140's entering.

In one embodiment, Table 1 can be stored in the integrated multi-media file mentioned above, or in an independent relation file. When the visual information is played, Table 1 can be restored from the abovementioned integrated multi-media file or the independent relation file. When user's cursor/finger/pen points to or floats on some regions, the electronic device can find the relation timings from Table 1 to play the audio related to the timings. The steps for playing audio could be automatic or wait for user's command.

In the present invention, the visual information includes the data being able to be displayed and be seen by user's eyes. The visual information could be the motion film, static film and/or integrated both of them. In the present invention, the visual information includes the meanings mentioned above.

When the region has several timings, the electronic device plays the audio related to the earliest timing automatically or let user select which timing's audio to be played. For example, when user's cursor/finger/pen points to or floats on region E5, two timings 00 h: 00 m:03 s:11 and 00 h:00 m:04 s:11 can be offered to user to select by. Also, region E7 has two timings 00 h:00 m:03 s:31 and 00 h:00 m:04 s:51 can be offered to user to select by.

In the embodiment mentioned above, the audio information played starts from recorded timing. However, in another embodiment, the audio information played could also start from a period before or after the recorded timing. For instance, playing the audio information starts from 2 seconds before the recorded timing.

The present invention does not limit to the time for the audio information played on the recorded timing. In some embodiments, the structure of the audio information or other limits could make error. For example, after the signal processes, such as sampling, encoding, and compressing, the audio information could be recorded in one-tenth of a second as one unit or in irregular period as one unit. In this case, although the timing recorded could be accurate to one-hundredth of a second, the audio information played cannot be played at the recorded timing exactly. Those skill in the art can realize that between the recorded timing and the timing of the audio information played allows error or can be adjusted. However, the audio information played according to the recorded timing, even having error or being adjusted, should be included in the present invention.

In the data structure of Table 1, the timings can be looked up from regions, and regions can also be reversely looked up from the timings. However, the reversal looking up mentioned above needs at least one inquiry to each line of Table 1. In another embodiment, the data structure shown in Table 2 can be created for looking up regions via timings.

TABLE 2 relating timing (corresponding) region 00h:00m:01s:11 C3 00h:00m:01s:21 B3 00h:00m:01s:31 B4 00h:00m:01s:41 B5 00h:00m:02s:11 B7 00h:00m:02s:21 B8 00h:00m:02s:31 B9 00h:00m:02s:41 C9 00h:00m:03s:11 E5 00h:00m:03s:21 E6 00h:00m:03s:31 E7 00h:00m:04s:11 E5 00h:00m:04s:21 F5 00h:00m:04s:31 F6 00h:00m:04s:41 F7 00h:00m:04s:51 E7

The recording position of Table 2 could be saved in the integrated multimedia file mentioned above, and could also be saved in an independent relation file, and even in the audio file. When the audio information is played, the Table 2 can be read from the abovementioned integrated multimedia file, independent relation file, or visual file. The relating region could be displayed on panel when audio is played between one timing and the next timing. For example, between 00 h:00 m:01 s:11 and 00 h:00 m:01 s:21, the region C3 can be highlighted; and between 00 h:00 m:01 s:21 and 00 h:00 m:01 s:31, the region B3 can be highlighted.

Those skilled in the art can realize the abovementioned highlighting can be achieved by many ways. For example, at least one method or the combination thereof as followings: displaying in different color or in glittering, line width-adding, region painting, and so on.

In the abovementioned embodiments, the touch traces are the traces on the visual files, and hence the regions in Tables 1 and 2 relate to touch points. In some cases, the touch traces and the traces on the visual files are different. Referring to FIG. 2, the touch traces and recorded traces for one preferred embodiment in accordance with the present invention is illustrated.

In the embodiment of FIG. 2, it includes 6 touch points 221 to 226 on touch panel/screen 200 and an arc 210. The arc 210's beginning point is the first touch point 221 and its ending point is the last touch point 226. When user draws the arc 210, pen or finger will pass through the 6 touch points mentioned above but the visual information only records the arc 210 and does not record the 6 touch points. Further, the abovementioned 6 touch points relate to 5 regions, that is, C1, B1, A2, B3, and B4. And, the arc relates to 5 regions C1, B1, B2, B3, and B4. It is clearly that the touch points 223 and 224 are in region A2 but the arc 210 does not pass through region A2. On the contrary, the arc 210 pass through region B2 but there is no any touch point in region B2.

Those skills in the art can realize that there are many ways for the visual information to record the arc 210. In some embodiments, they record each point included in the arc 210. In other embodiments, they record the beginning and the ending positions of the arc 210, and the radian and the middle position of the arc 210. In the embodiment of FIG. 2, only the arc 210 is taken as the example but those skills in the art can realize that there are many cases showing the touch traces being different to recorded traces. For example, circle, rectangle, square, polygon, and so forth, the touch traces thereof are different to recorded traces thereof. Furthermore, after combining several touch traces, the electronic device can recognize them as characters to save as recorded characters.

In one embodiment, all regions passed by the arc 210 could all relate to the timing of the beginning point 221. Referring to Table 3, the embodiment of the arc 210 is recorded according to the form of Table 1. It can be find that the relating timings of these regions are the same. In this way, whatever which region is selected, the audio information of the timing related to touch point 221 is played.

TABLE 3 region relating timing (corresponding) B1 00h:00m:01s:11 B2 00h:00m:01s:11 B3 00h:00m:01s:11 B4 00h:00m:01s:11 C1 00h:00m:01s:11

Similarly, Table 3 can be transferred into Table 4 using timings to relate to regions. In other words, when the audio information is played to the relating timing, the 5 regions in which the arc 210 locates will be highlighted.

TABLE 4 relating timing (corresponding) region 00h:00m:01s:11 B1 00h:00m:01s:11 B2 00h:00m:01s:11 B3 00h:00m:01s:11 B4 00h:00m:01s:11 C1

Referring to FIG. 3, the traces for one preferred embodiment in accordance with the present invention are illustrated. Comparing to FIG. 1, the touch panel/screen 300 in FIG. 3 does not separate into several regions and user still draws 4 traces 310-340.

In one embodiment, these traces 310-340 could be touch traces or could also be the traces recorded by the visual information. The timing related to each trace is the timing of the first touch point for forming each trace detected by the electronic device. The present invention does not limit to how to record these traces 310-340. In one case, the trace can be presented by recording the coordinate position of each touch point. In another case, the trace can be presented by recording at least one coordinate position and at least one geometry parameter, such as recording the center coordinate of circle and the radius thereof. It is noticeable, the first touch point of the circle trace is not always the circle center, and that is, the coordinate of the touch point is not necessarily recorded.

Referring to Table 5, it shows a reference for the traces and the relating timings. It can be put in order by the sequence of the traces or by at least one coordinating of the traces.

TABLE 5 relating timing (corresponding) trace 00h:00m:01s:11 310 00h:00m:02s:11 320 00h:00m:03s:11 330 00h:00m:04s:11 340

When the audio information is played, after one relating timing and before the next relating timing, the relating trace can be highlighted. For example, after the timing 00 h:00 m:01 s:11 and before the timing 00 h:00 m:02 s:11, the trace 310 can be highlighted. In a variation of Table 5, each trace can still relate to the timing of ending. In another variation of Table 5, several traces can be combined into a trace sign to use a field to present the beginning and/or ending timings related to several traces.

On the contrary, when user selects one trace of the visual information, such as trace 320, the electronic device plays the audio information form the relating timing 00 h:00 m:02 s:11. It's worth noting and those skilled in the art can realize that there are many ways to achieve selecting one trace. For example, touching on the trace, touching on some area of the trace shape, touching on the area surrounded by the trace, touching on some shape area extended by the trace can select the trace.

In the embodiment of FIG. 3, the traces 330 and 340 are mixed on points 331 and 332. In one embodiment, when the point 331 or 332 is touched, user could select to play the audio information of the two timing related to traces 330 and 340. In another embodiment, when the point 331 or 332 is selected, user could not select to play the audio information but could be enforcing to select the un-mixed part of the trace 330 or 340.

The processing device 430 further includes an interface 431 to connect with the touch device 410, a timing generating module 432 to generate timing(s), and a processing module 433. In one embodiment, the processing device 430 could directly connect to the touch device 410 to receive the relating information of the touch point. The timing generating module 432 could receive clock signal or time signal to generate timing to the combination of software, hardware, or firmware of the processing module 433. The processing module 433 could be a calculating unit for performing the operating system, driving programs, and/or application programs of the recording system.
